Try other context lengths

Run it with Ollama

With Ollama installed, one command downloads and starts Phi-4 Reasoning 14B:

ollama run phi4-reasoning:14b

Ollama's default download is Q4_K_M (about 11.2 GB here). You have room for Q6_K, which is excellent: pick that GGUF in LM Studio or from Hugging Face.
